Description
Technical field
The present invention relates to one and be applied to the industries such as oil, chemical industry, metallurgy, electric power, complete the condensation of process heat medium or cooling equipment, specifically a kind of precooling humidification evaporation air cooler.
Background technology
At present, due to water conservation, adopt cooling the obtaining of air to apply more and more widely, known air cooler is mainly dry type air cooling pattern, and mainly, by the augmentation of heat transfer cooling medium of finned tube, medium is cooling by air, has saved cooling water.But require low situation for outlet temperature, dry air cooling is difficult to meet the demands.Since entering last century, a kind of evaporative air-cooling is used widely, it takes away the principle of the evaporation latent heat outside pipe by circulated sprinkling water from top to bottom and air from top to bottom, processing medium can be cooled to approach environment wet-bulb temperature, good cooling results, and floor space is little.What the surface evaporation air cooler evaporative air-cooling of patent 96200559.2 adopted is a kind of light pipe is as heat exchange element, and what upside precooling adopted is the dry and cold device of the horizontal fin tube type of a slice.Known other this structure of evaporation air cooler fundamental sum is similar both at home and abroad, all exists water spraying time long, the problem that water saving degree is not high.
Summary of the invention
Technical problem to be solved by this invention is: be to provide a kind of structure simpler, heat transfer efficiency is higher, and unit heat exchange area is large, and in 1 year, water spraying time is short, the more evaporating air cooler of economizing on water.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of precooling humidification evaporation air cooler is provided, formed by pre-cooler tube bundle, evaporative air-cooling tube bank, blower fan, mist eliminator, water injector, water circulating pump, water tank, blower fan is located at mist eliminator top, mist eliminator is in the middle of blower fan and water injector, evaporative air-cooling is restrained below water injector, water tank is established in evaporative air-cooling tube bank below, the invention is characterized on a kind of air intake passage of precooling humidification evaporation air cooler spray equipment is set; Air intake passage comprises evaporative air-cooling tube bank below, air feed shutter is side and air feed shutter window inner side outside window, spray equipment can be located at a place or the many places of air intake passage, i.e. evaporative air-cooling tube bank below, and air feed shutter is a place or the many places of side and air feed shutter window inner side outside window.Feature of the present invention is also to arrange pre-cooler tube bundle and carries out coolingly in advance, and the heat exchanger tube of pre-cooler tube bundle can adopt finned tube.
The invention is characterized in that a kind of precooling humidification evaporation air cooler can arrange spray equipment between pre-cooler tube bundle and mist eliminator.Spray equipment can be atomizing spray, is made up of water inlet pipe and spray nozzle, and feature of the present invention is also that spray nozzle has spiral channel.Feature of the present invention is also that the spray equipment on air intake passage and the spray equipment between pre-cooler tube bundle and mist eliminator can arrange simultaneously, also can arrange respectively.Feature of the present invention is also that steam-generating bank can arrange water treatment facilities to the water inlet pipe between pre-cooler tube bundle.The bobbin carriage of steam-generating bank of the present invention and pre-cooler tube bundle can adopt threaded plug type, cover-plate type and set tubular type, and the heat exchanger tube of steam-generating bank and pre-cooler tube bundle can be U-shaped coil pipe, can be also straight tube.
Operation principle of the present invention is: in the time of summer high temperature, first processing medium enters pre-cooler tube bundle, under the wind effect of blower fan, carries out precooling, be cooled under uniform temperature, then enter steam-generating bank, in steam-generating bank, flow, open steam-generating bank top water injector, shower water is in the export-oriented current downflow of evaporation tube beam tube, air flows from bottom to top outside pipe simultaneously, and the heat of pipe inner side, by means of the water in pipe outside, pass to air, and be discharged in air.In the time that spring and autumn equitemperature is more gentle, close steam-generating bank top water injector, start the spray equipment of air intake passage, air intake passage spray equipment is made up of water inlet pipe and spray nozzle, current form spiral flow from the spiral channel of spray nozzle, in spiral flow, be formed centrally parital vacuum, make current and the violent friction of distinguished and admirable generation, the rapid vaporization of a small amount of water, absorb heat around simultaneously, make water and air temperature around reduce rapidly temperature, the reduction of air themperature from bottom to top, form the larger temperature difference with steam-generating bank, under low temperature wind action, processing medium in cooling tube, play the cooling effect of atomization humidification, greatly save cooling water, simultaneously owing to only having adopted atomization humidification cooling, power of fan reduces greatly, save electricity consumption.If it is very tight that outlet temperature requires, can between pre-cooler tube bundle and mist eliminator, spray equipment be set, under extreme high-temperature condition, can open steam-generating bank top water injector, start steam-generating bank cooling effect, open the spray equipment between spray equipment and pre-cooler tube bundle and the mist eliminator of air intake passage simultaneously, air intake passage spray equipment makes water and air temperature around reduce rapidly temperature, cooling effect is better, spray equipment between pre-cooler tube bundle and mist eliminator, identical with air intake passage spray equipment principle, reduce the EAT of pre-cooler tube bundle, make pre-cooler tube bundle cooling effect better, make under the condition of extreme high temperature, should be able to strict guarantee medium cooling.When winter air temperature is lower, stop water spray, adopt dry and cold.Said structure can be realized by season and control water spray, plays the effect of water saving and economize on electricity.
